Updating sensors works only on 2 out of 4


#1

I was requesred to update my sensors from version 8 to 9. It worked fine for 2 sensors. The other 2 sensors turned the red light on. I cannot turn off the sensors other then let the battery go down. Is there any help?

If I hold the button for a longer time the light turns green. No blue tooth connection can be established. I cannot get a yellow light. Holding down while the green light is on returns to red again.

Hey! When you see the green color does it stay that color when you move it around? If so it could be in update mode. Typically it is yellow and when you restart the Sensorware app it should detect your sensor in update mode.

Try that and see if it works.
